ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

Objective:To explore the impact of different six-character qigong training modes on respiratory muscle function early after a stroke.Methods:Sixty-six stroke survivors in the early stage of recovery were randomly divided into a control group, a modified training group, and an ancient training group, each of 22. In addition to routine rehabilitation training, the control group received conventional respiratory training. The modified training and ancient training groups were trained in modified six-character qigong or ancient six-character qigong, respectively, for two weeks. Before the treatment, after the two weeks and one month later, maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), forced expiratory volume in one second, forced vital capacity, peak expiratory flow, maximum mid-expiratory flow, and peak inspiratory flow were measured. Diaphragm mobility during quiet inspiration and maximum inspiration were also quantified.Results:After 2 weeks of treatment and at 1 and 3 months after the end of the treatment, all three groups showed significant improvement in MIP, MEP and the pulmonary ventilation indicators, but the average improvement in the modified training group was significantly greater than in the other two groups. Their average diaphragm mobility was also significantly greater.Conclusion:Modified six-character qigong respiratory training is more effective than its ancient counterpart in improving respiratory muscle function, pulmonary ventilation, and diaphragm mobility early after a stroke, with effects which persist for at least one month.

OBJECTIVE To explore the mechanism of steam-processed Polygonatum sibiricum polysaccharides(SPSP) in prophylaxis and treatment of mice with blood deficiency syndrome(BDS) by RNA sequencing(RNA-seq) technology. METHODS The mice were randomly divided into five groups(10 mice in each group), namely normal group, model group, SPSP groups(0.1, 0.4 g·kg−1), Danggui Buxue oral liquid(DOL) group. BDS model was induced in mice by acetylphenyl-hydrazine and cyclophosphamide. Blood routine, body weight and body temperature were tested after a consecutive administration for 14 d. The differential expressed genes(DEGs) related to anti-BDS by SPSP were screened through the transcriptome sequencing of the hepatic tissue in BDS mice. Functional annotation and enrichment analysis were performed to screen out the gene expression signaling pathways related to the treatment of SPSP on BDS mice. Quantitative polymerase chain reaction(qPCR) was used to verify the experiment. RESULTS Compared with the model group, SPSP(0.4 g·kg−1) could elevate the blood routine indexes such as red blood cell, white blood cell, hemoglobin, platelet, mean corpuscular hemoglobin concen-tration(P<0.01), and reverse the body weight and body temperature to normal(P<0.01 or P<0.05). The result of transcriptomic analysis showed that the underlying mechanism was mainly related to hematopoietic cell line, retinol metabolism, steroid hormone biosynthesis, platelet activation, B cell receptor signaling pathway, and leukocyte transendothelial migration, etc. The result of qPCR showed that SPSP(0.4 g·kg−1) could elevate the expression of JAK1, STAT1 and GATA1 mRNA (P<0.01 or P<0.05). CONCLUSION SPSP has therapeutic effects on BDS. The key DEGs in the treatment of BDS by SPSP are mainly related to the restoration of hematopoietic function, regulation of hormone and immune function. The mechanism of SPSP on treatment of BDS might be the regulation of JAK1/STAT1 signaling pathway.

Objective:To study the iodine nutrition status of key populations in Sichuan Province, so as to provide a basis for scientific supplementation of iodine and adjustment of prevention and control measures.Methods:From 2018 to 2022, the stratified cluster sampling method was used in 21 counties (district) in Sichuan Province. Each county (district) was divided into 5 areas based on east, west, south, north, and center. One township (street) was selected as a monitoring site from each area. Forty children aged 8 - 10 years old and 20 pregnant women, women of childbearing age, lactating women, and their infants and young children (0 - 2 years old) were randomly selected from each monitoring site. Household edible salt and urine samples were collected for salt and urine iodine testing. B-ultrasound method was used for thyroid examination in children.Results:A total of 52 019 samples of edible salt were collected, including 50 084 qualified iodized salt samples. The qualified iodized salt consumption rate was 96.3%, and the median salt iodine was 27.1 mg/kg. A total of 21 021 urine samples from children were tested, with a median urine iodine level of 199.5 μg/L. A total of 10 293 urine samples were taken from pregnant women, and the median urine iodine level was 172.6 μg/L. A total of 10 502 urine samples were taken from women of childbearing age, with a median urine iodine level of 174.4 μg/L. A total of 10 444 urine samples were taken from lactating women, and the median urine iodine level was 164.9 μg/L. There were 10 442 urine samples from infants and young children, and the median urine iodine level was 191.9 μg/L. A total of 21 028 children underwent thyroid examination, with a goiter rate of 1.8% (370/21 028).Conclusion:From 2018 to 2022, the iodine nutrition of key populations in Sichuan Province is at an appropriate level, and the elimination of iodine deficiency disorders continues to be maintained.

Objective To investigate the effects of Carthamus tinctorius L.extract(CTLE)on the levels of oxidative stress and inflammation in mice with ethanol-induced alcoholic liver disease and its mechanism of action.Methods SPF-grade C57BL/6 male mice were randomly divided into four groups:control group,model group,low-CTLE group(50 mg·kg-1),and high-CTLE group(100 mg·kg-1).The control group was given Lieber-Decarli liquid diet,and the other groups were given Lieber-Decarli alcohol diet to construct a chronic alcoholic liver injury model in mice.Serum and liver tissues of mice were collected and serum biochemical indexes of mice were detected.HE and oil red O staining were applied to observe pathological changes in mouse liver tissues.Real-time fluorescence quantitative PCR and Western Blot were used to detect the mRNA and protein expression levels of Keap1/Nrf2 and STAT3/NF-κB pathway-related factors.Results Compared with the model group,the ALT,AST,LDL-C,and MDA levels were significantly reduced(P＜0.05,P＜0.01),while the levels of HDL-C,SOD,and GSH were increased dramatically in the administered group(P＜0.05,P＜0.01),which indicated that CTLE has specific protective and antioxidant effects on alcoholic liver injury in mice.HE staining and oil red O staining showed that the hepatic lesions and lipid deposition of mice were ameliorated.It enhances the antioxidant and anti-inflammatory effects of the body by activating the mRNA and protein expression levels of antioxidant factors related to the Keap1/Nrf2 pathway and inhibiting the mRNA and protein expression levels of inflammatory factors related to STAT3/NF-κB pathway(P＜0.05,P＜0.01).Conclusion It was shown that CTLE could exert anti-oxidative stress and anti-inflammatory effects through regulating Keap1/Nrf2 and STAT3/NF-κB signaling pathways to attenuate alcoholic liver injury in mice.This study may provide a new idea for the treatment of alcoholic liver disease and the subsequent study of molecular mechanisms.

The fall armyworm (FAW), Spodoptera frugiperda, is a destructive pest native to America and has recently become an invasive insect pest in China. Because of its rapid spread and great risks in China, understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies. Here, we assembled a chromosome-level genome of a male FAW (SFynMstLFR) and compared re-sequencing results of the populations from America, Africa, and China. Strain identification of 163 individuals collected from America, Africa and China showed that both C and R strains were found in the American populations, while only C strain was found in the Chinese and African populations. Moreover, population genomics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations. Taken together, FAWs invaded into China were most likely originated from Africa. Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW, of which 283 genes are specific to FAW. Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles, and several detoxification genes such as AOX, UGT and GST specially responded to the pesticides. These findings will be useful in developing effective strategies for management of FAW in China and other invaded areas.

Objective:To investigate the influencing factors of headache degree in migraine patients with patent foramen ovale (PFO).Methods:The clinical data of 124 migraine patients with PFO from January 2013 to June 2019 in Dalian Central Hospital Affiliated to Dalian Medical University were retrospectively analyzed. The right-to-left shunt of PFO was assessed by contrast-enhanced transcranial Doppler (c-TCD); the diameter of PFO, length of PFO tunnel and the presence of atrial septal aneurysm (ASA) were detected by transesophageal echocardiography (TEE); the degree of migraine was assessed by headache impact test-6 (HIT-6) scale. The relations between right-to-left shunt volume of PFO, diameter of PFO and degree of migraine were analyzed by Goodman-Kruskal γ test; the relations between the length of PFO tunnel, ASA and degree of migraine were analyzed by Spearman rank correlation analysis.Results:Among the 124 migraine patients with PFO, the c-TCD test result showed that small shunt volume was in 20 cases, medium shunt volume in 31 cases, and large shunt volume in 73 cases. The TEE test result showed that small foramen ovale in 76 cases, medium foramen ovale in 47 cases, and large foramen ovale in 1 case; long tunnel in 57 cases, and short tunnel in 67 cases; without ASA in 91 cases, and with ASA in 33 cases. The HIT-6 score result showed that some influence in 9 cases, significantly influence in 22 cases, and serious influence in 93 cases. The Goodman-Kruskal γ test result showed that right-to-left shunt volume of PFO and diameter of PFO were positive correlation with degree of migraine ( γ = 0.66, P<0.01; γ = 0.38, P<0.05). The Spearman rank correlation analysis result showed that ASA was positive correlation with degree of migraine ( r = 0.18, P<0.05), while the length of PFO tunnel was negative correlation with degree of migraine ( r = -0.23, P<0.05). Conclusions:The right to left shunt amount of PFO, diameter of PFO and the presence of ASA are positive correlation with degree of migraine, while the length of PFO tunnel is negative correlation with degree of migraine.
